PAPER VESSEL.

sPEdIFxcArIoN forming part of Letters Patent No. 656,439, dated August 21, 19610,

Application filed June 1 l, l 900.-

To all whom it may camera.-

Be it known that I, J OHN N. DAvis, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Paper Vessels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to paper vessels designed for liquids, oysters, berries, ice cream,

and the like; and the special object of the invention is to provide a vessel which can be filled and handled with liquid material Without leaking or spilling and which when closed shall be slop-proof; second, to so fold the top that a very cheap and effective fasteningmay be used to lock the top shut; third, to provide such thick and heavy folds for the sides of the top that the top will fold down naturally and easily into the proper position, theside.

folds forming a break or folding edge for the top covers.

In the drawings, Figure 1 is a plan view of the blank from which the vessel is folded. Fig. 2 is a perspective View of the vessel closed. Fig. 3 is a side. elevation of the vessel open,

with part of the side wall cut away toshow' the interior fold. Fig.4 is a detail central vertical section of the upper side edge of the vessel when closed, taken on the lines 4 4 of creased with fold-lines between the various parts, as shownin the drawings in Fig. Land in addition the corners between the sides);-

tensions F F and the extension folds H H are creasedwith thediagonal score-lines a b.

The blank isthen ready for-folding, and the sides and ends are brought into upright position and the corner folds D E folded over on the outside, so as to overlap, as shown in Figs. 2 and 3. In this position the'sideand end extensions F and G and the extension folds H and I will stand up in vertical posimade up of bet The sides are Serial No. 19 ,813. No model.)

tion, extending abovethe top line f of the ves sel, the end extensions G G forming a single continuous wall with the ends 0 C, while the side extensions F F form a single continuous wall on the" inside with the sides B B. The triangular folds at the corners between the sideextensions F F and the extension folds H H are then folded outwardly on the score lines a b, as shown in Fig. 3, and We then have a heavy triangular fold at the upper portion of the sides of the vessel. The ends of the bail L are then inserted through the folds D E at the points at, so as not to pierce the sides B B, and strips of tin M are inserted through the overlapping extension folds H I and the sideextensions F F atthe points e e. These strips of tin M are clenched on the inside and folded down on theoutside flat with the extension folds,.as shown in Fig. 3. In

this way the various overlapping'side folds ing the end extensions G G to fold down on top on the score-lines c 0. These end extensionsG G are formed of such a width that they will overlap, and the folding down of thesides will leave the strips of tin M M- extending out horizontally, as shown by the dotted line g in Fig. 4. The strips of tin are then bent upover the overlapping edges of the end extensions G G, as shown at [thin Fig. 2, and the paper vessel is securely closed and locked.

The special features of importance in my improved paper vessel consist in the heavy triangular foldsthat are formed on the sides and in the folding down of these sides, so as to bring the end extensions together and cause them to slightly overlap, the weight of material in the sides renderingit a very sim ple and easy operation to thus close the vessel. in addition to this the tin strips which look the side folds together are thus brought by the folding in of the sides in a perfectly- -horizontal position, to be instantly folded over the overlapping edges of the end extensions to lock the cover into place. In this way an absolutely slop-proof vessel is obtained.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A paper vessel, formed from a single blank of paper, having, bottom, sides and ends, side and end extensions with extension folds between them, the side extensions and the adjacent extension folds being turned over at the corners outwardly, and the extension folds adjacent the end extensions foldinginwardly on a diagonal line,said blank being folded into shape in the manner described, in'which the side extension portions are folded inward with the end extensions overlapping on the outside, and means for locking together the overlapping end extensions to close the vessel, substantially as shown and described.

2. A paper vessel, formed from a single blank of paper, having bottom, sides, and ends, with side folds between the sides and ends, side and end extensions with end extension folds between them, the side extensions and the adjacent extension folds being turned over at the corners outwardly, and the extension folds adjacent to the end extensions folding inwardly on a diagonal line, said blank being folded into shape in the manner described, in which the side extension por tions are folded inward with the end extensions overlapping on the outside, and strips of tin passing through the side extension portions, clenched on the inside and lying fiat along the outside, whereby when the side extension portions are folded in and the end extensions overlap, the strips may be bent over the overlapping portion, to close the vessel, substantially as shown and described.
